Working principle

This hearing aid consists of a microphone, an analog-to-digital converter, a digital signal processor, a digital-to-analog converter, a receiver and other components. The principle is that the analog-to-digital converter converts the analog signal generated after the sound wave is received by the microphone into a digital signal. The digital signal processor performs various digital processing, and then uses the digital-to-analog converter to convert the digital signal back to an analog signal. The receiver converts the analog signal The echo signal is converted into an echo signal, and then the sound signal is transmitted to the user’s ear canal. The entire process uses digital signal processing technology to digitally complete the functions originally implemented by various electronic devices in analog hearing aids. It has higher comfort and better flexibility, thereby improving and enhancing the hearing of hearing-impaired patients.

Application scenes

Wearing a hearing aid

1. Step 1:Pinch the receiver tightly with your hand and gently insert the earplug into the ear canal.
2. Step 2:Hang the hearing aid behind the ear and adjust the position of the hearing aid to a comfortable position.

Replace hearing aid earplugs

Inappropriate earplugs may cause howling and swelling, so we recommend that you replace them with appropriate earplugs.

1. Step 1: Turn the edge of the earplug upside down, hold the hearing aid receiver with one hand and pull the earplug down with the other.
2. Step 2:Select the earplug that fits your ear canal, align the receiver and insert it.

Note: After installing the earplugs, gently pull the earplugs to ensure that the earplugs are firmly installed and not easy to fall off.

Replace wax guards

The wax guard filter is located in the sound hole of the hearing aid which can effectively prevent the cerumen from entering into the hearing aid to cause damge to the hearing aid. Please replace the wax guard filter every 3 months and do not reuse the used filter.

1. Step 1:Remove earplugs first. See “Replacing Hearing aid Earplugs”.
2. Step 2:Align the sound hole with this notched side and insert.
3. Step 3:Pull out the notched side with the used filter, if the used filter has not been pulled out, repeat last step.
4. Step 4:Insert the other end with the new filter into the sound hole.
5. Step 5:Pull out the installing end and a notched side will be exposed when the new filter is successfully installed.
